Title: Valve moving device for internal combustion engine
Inventor: HONMA MASAYUKI
IPC: F01L1/12
Filed: 1981-04-07
Abstract: PURPOSE:To automatically absorb the backlash of an intake and an exhaust valves, by providing hydraulic pivots for the fulcra of rocker arms of central pivot type. CONSTITUTION:Hydraulic pivots 36A, 36B are automatically adjusted so that they elongate depending on the backlash of an intake and an exhaust valves 43, 44 to make the clearance zero. Since rocker arms 35A, 35B are supported at their central parts by the pivots 36A, 36B, the rocking leverage can be made sufficiently large without increasing the length of the rocker arms. Since the hydraulic pivots 36A, 36B do not move as members of a valve moving mechanism, the inertial mass is not increased.

Title: Flexible magnetic disc
Inventor: OKUZAWA YASUTOSHI
IPC: G11B17/03
Filed: 1983-03-29
Abstract: PURPOSE:To prevent eccentricity of a flexible magnetic sheet when it is loaded by applying a lubricant layer into a ring shape on front and rear faces of the sheet along the circumferential edge of the center hole of the sheet to reduce the coefficient of friction between the sheet and a positioning member. CONSTITUTION:When a flexible magnetic disc is loaded to a device, a rotating part 3 of the positioning member is applied to from below a sheet 2, and a collet 4 is allowed to fall from above this rotating part 3 and is press-fitted into a round recess part 3a of the rotating part 3. At this time, if there is a positional deviation between a round hole 2a of the sheet 2 and the round recess part 3a of the rotating part 3, a part of the circumferential edge of the round hole 2a of the sheet 2 is held between the collet 4 and the recess part 3a of the rotating part 3, and the sheet 2 is rotated in the eccentric state. Therefore, the lubricant layer is applied into a ring shape on front and rear faces of a sheet 10 along the circumferential edge of a center hole 10a of the sheet 10 to reduce friction between the sheet and the positioning member, and thus, the sheet is pressed to the slope of the collet and is set to the center position when it is positioned, and eccentricity is prevented.

Abstract: PURPOSE:To prevent an identification (ID) code from being mixed and to correctly read out the ID code by using a means for sending the ID code from the monitor controller side and a means for sending the ID code from the ID card side based on a code request. CONSTITUTION:In a noncontact ID system to be used for a system for managing the entrance and exit to/from a managed place, partial ID codes assigned to ID bodies to be especially frequently going in and out are successively transmitted from a monitor controller prior to the deciding operation of the ID body based on the transmission/reception of a response signal including a code request signal and its own ID code and the ID card receiving the ID code decides whether the received ID code coincides with its own ID code or not. At the time of coincidence, a 1st response signal is sent and the monitor controller executes recognizing and deciding processing based on the reception of the 1st response signal. Consequently, plural ID codes entered into a detecting area can be correctly read out.
